If you are relatively healthy and active, not imminently; not necessarily. However as you continue to get older and your heart grows naturally weaker with age in addition to less activity and more sedentary lifestyles, yes. It is important to drink plenty of fluids, stay as active as possible, reduce stress, and if you have frequent A-fib symptoms it wouldn't hurt to supplement yourself with low-dose aspirin to reduce the chance of blood clots. Consult your Doctor first however. Good luck, stay healthy. Enjoy the life we are given.
